Abstract
The utility model relates to a bearing structure for preventing height increase of a high temp multi-stage oil pump after heated which includes a base, a pump shaft, a water inlet section, a water outlet section and a supporting frame. The bearing structure is characterized in that: the supporting frame is fixed with the water inlet section, and the water outlet section by bolts, and the connection surface is the horizontal plane of the pump axes; a cooling chamber which is connected with a cooling water inlet pipe is provided on the supporting frame. The advantages of the bearing structure are: the supporting frame temperature and the height of the pump center will not change basically when the temperature of the pump which is heat is increased, thus, the coaxiality and gap between the pump shaft and the electric motor shaft are ensured and the normal running of the pump is also ensured.
Description
Technical field
The utility model relates to a kind of supporting structure, particularly a kind of supporting structure that prevents that the multistage oil pump of high temperature is heated afterwards highly to be increased.
Background technique
The multistage oil pump of part high temperature adopts inlet segment at present, water exit end and support supporting way integratedly support pump but there is following shortcoming in this structure: when oil pump is carried high temperature media, whole pump can be heated, inlet segment increases together with its upper bracket size of can being heated, size also can increase after water exit end was heated together with its upper bracket, if inlet segment support and water exit end support are fixed with base respectively, after then it is heated, water inlet-outlet segment and its upper bracket can make the center height of whole pump increase along the hot increasing amount of short transverse, like this, the concentricity of pump shaft and motor shaft changes, thereby can influence the operation of entire pump.
Summary of the invention
The purpose of this utility model is to solve the multistage oil pump of high temperature in the prior art to be in operation and to be subjected to high temperature to take place highly to increase and to cause the concentricity of pump shaft and the motor shaft existing problem that changes, and a kind of multistage oil pump of high temperature highly supporting structure of increase of back of being heated that prevents is provided.The utility model design prevents the supporting structure that the multistage oil pump of high temperature is heated afterwards highly to be increased, comprise base, pump shaft, inlet segment, water exit end, support, it is characterized in that: support is connected by bolt with water exit end with inlet segment, junction surface is the horizontal plane of the pump shaft heart, on support, be provided with cooling chamber, be connected to cooling water turnover pipe on the cooling chamber.The utility model has the advantages that to enable after pump is heated intensification that its backing temp is constant substantially, the center height of pump is also constant substantially, has guaranteed the concentricity and the gap of pump shaft and motor shaft, has guaranteed that also water pump ground runs well.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is the horizontal schematic representation of structure of the present utility model,
Embodiment
Comprise base 1, pump shaft 2, inlet segment (marking on the figure), water exit end (marking on the figure), support 3 among the figure, it is characterized in that: support 3 is fixedlyed connected by bolt 4 with water exit end with inlet segment, junction surface is the horizontal plane of pump shaft 2 hearts, on support 3, be provided with cooling chamber 5, be connected to cooling water turnover pipe 6 on the cooling chamber 5.
Because it is inlet segment and support 3, water exit end and the support 3 of the multistage oil pump of high temperature is independent respectively, can add cooling chamber 5 on support 3 like this cools off, avoid the thermal change amount of support 3, the Support Position of inlet segment and support 3, water exit end and support 3 is on shaft axis in addition, avoided inlet segment, water exit end in the hot increasing amount of this part along short transverse, a whole like this pump reduces along the hot increasing amount of short transverse, guaranteed the concentricity and the gap of pump shaft 2 and motor shaft, guaranteed that also water pump ground runs well.
